Phosphor screen substrate, image display device using the same, and manufacturing methods thereof

Abstract

An object of the present invention is to provide a phosphor screen substrate in which various properties can be fulfilled, for example, withstand voltage properties are superior, white uniformity of display image is superior, and luminescence can be efficiently reflected toward the front side. A method for manufacturing a phosphor screen substrate, according to the present invention, comprises the steps of: forming a resin layer on a phosphor layer disposed on a substrate; heating the resin layer to a temperature in the range of from a glass transition temperature of a resin forming the resin layer to the melting point thereof; forming a metal film on the heated resin layer; and removing the resin layer provided with the metal film thereon by pyrolysis.

1 - 7 . (canceled)  
   
   
       8 . A phosphor screen substrate, comprising: 
 a substrate;    a phosphor layer provided on said substrate; and    a metal film provided on said phosphor layer, wherein    the difference in height of said metal film on said phosphor layer is in the range of 20% to less than 100% of the a median of distribution of phosphor particles forming said phosphor layer.    
   
   
       9 . An image display device, comprising: 
 electron sources; and    a phosphor screen substrate which is disposed so as to oppose said electron sources and which has a phosphor layer, wherein    said phosphor screen substrate is a phosphor screen substrate according to  claim 8.
